Abstract: ABSTRACT OF THE INVENTION      This invention relates to a process of preparing aqueous slurries of vesiculated granules of crosslinked polyester resin wherein the granules have a maximum shrinkage on drying of 5% of the granule diameter.     Previously-known processes for the preparation of granules of this type have utilised polyamines; this has led to odour and colour problems.  These problems may be eliminated or substantially reduced by the use of bases which are metal oxides, hydroxides or salts wherein the metal cation is selected from Ca, Mg, Ba, Ti, Zn, Pb, Sr and Co and, when a metal salt is used, the pKa value of the conjugate acid of the anion is greater than 2.     The resulting granules are useful as matting and opacifying agents in, fur example, paint compositions.

Abstract: Abstract of the Disclosure:       The present invention relates to a method of making a multi-layer ceramic capacitor and, in its more particular. phases, to a capacitor having closely predictable tolerances.          The method comprises the steps of providing or fabricating green ceramic sheets and imprinting or otherwise depositing on such sheets patterns of electrode material, the patterns each defining a continuous electrode area many times the anticipated area of the final capacitor.  A multiplicity of layers of the ceramic and electrode are stacked and increments of the composite mass are cut therefrom in the direction perpen-dicular to the axis of elongation of the electrodes, which increments are thereafter fired, terminated and glazed or enveloped in an insulating coating whereby there are formed capacitors which are substantially marginless, i.e. do not include borders of ceramic material projecting beyond the electrode area.  Preferably the capacitors are fabricated to value by severing an increment of predetermined width, finishing a capacitor therefrom and measuring its value, and thereafter sizing the subsequently severed increments as a function of the capacitance measurement derived.

Abstract: INVENTOR:  WALTER REIST          INVENTION. APPARATUS FOR REMOVING FROM A PRODUCT STREAM            CONVEYED BY MEANS OF A CONVEYOR DEVICE FLEXIBLE FLAT PRODUCTS, ESPECIALLY PRINTED PRODUCTS     ABSTRACT OF THE DISCLOSURE          Two stop or impact members which are situated opposite one another with respect to grippers of a conveyor device are used for detaching or removing the printed products out of their product formation.  In their effective position these stop members project into the conveying path of the printed products.  The printed products released by the grippers impact against the stop members and under the action of their own weight drop downwards.  Viewed in the conveying direction the printed products are folded or bent into a substantially saddle-like configuration forwardly of the stop members, resulting in stiffening of the thus folded printed products, and after they impact against the stop members they can fall downwardly along a straight path.  In order to appropriately kink or bend the printed products there is provided a substantially saddle-shaped support upon which come to bear the printed products at the region of their trailing edge, these printed products being retained approxi-mately at their central region by the grippers at their leading edge.  The printed products also can be released from the conveyed product formation or stream along a very short path even when the conveyor device is operating at high conveying speeds.

Abstract: TRANSMISSIVE HOLOGRAPHIC OPTICAL  ELEMENT ON ABERRATING SUBSTRATE              Abstract of the Disclosure An inexpensive, high quality transmissive holographic optical element and method for making are described.  The holographic optical element consists of a potentially aber-rating substrate which supports a layer of holographic re-cording material.  The material contains a recorded fringe pattern that cancels the aberrations induced in an image wavefront as it passes through the aberrating substrate.          This optical element is formed by a method having the fol-lowing steps.  A first wavefront from a source, for example a point focus, is passed through the aberrating substrate, becomes distorted, and then passes through the holographic recording material to a wavefront conjugator. The conjugator launches a conjugate of the distorted wavefront back to the holographic recording material.  A second wavefront is then passed through the holographic recording material to form a fringe pattern or hologram as a result of the interference of the conjugate waveform and the second waveform.  Subse-quently, the developed holographic optical element is illu-minated with a reconstruction wave which is the duplicate of the reference wave.  Passage of this reconstruction wave through the holographic layer results in an emerging wave-front identical to the conjugated distorted wavefront which is then converted to the original wavefront as it passes through the aberrating substrate.

Abstract: ABSTRACT OF THE DISCLOSURE Shunt currents which flow between the electrodes of adjacent cells through the moving conductive fluid and the fluid pool in the manifold of a bipolar cell assembly are minimized by introducing the conductive fluid at the top of an elongated outlet manifold. This results in cascaded flow which interrupts the current path. Shunt currents between fluid manifold walls of the conductive bipolar elements in the series connected electrochemical cell assemblies are minimized by insulating the manifold walls with insulating, elastomeric sealing grommets. This prevents current flow between the manifold walls through the electrically conductive fluid in the manifold and provides an edgeseal between bipolar plates.

Abstract: ABSTRACT OF THE DISCLOSURE A method for forming a colored image in a limited area of a vision-corrective soft contact lens.  In one method, the lens is soaked in a diazonium salt and then exposed to actinic light through a mask which transmits light only to the non-image area of the lens.  Then, the unexposed image area is deve-loped by contact with an azo coupler.  In a second method, the diazonium salt is soaked in a gel relief of the desired image configuration and contacted with the lens.  The image is developed by soaking in the azo coupler.  In a third method, the diazonium salt, azo coupler, and a coupling inhibitor (a pH reducing agent) are premixed and applied by the gel relief.  The image is then developed by raising the image pH level as by contact with ammonia gas.  Also, apparatus for precisely contacting the lens with the gel relief image.                                          .

Abstract: ABSTRACT           This invention is a digital phase modulator for microwave transmitter systems.  A digital signal is bandwidth limited at baseband, then is shaped to compensate for the nonlinear reflection coefficient versus bias voltage characteristics in a phase modulator.  The shaped signal is applied to the phase modulator to modulate a carrier.  The carrier signal is derived from a high power amplifier operating at its maximum power handling capability.  Linear multiplication is then obtained, and use of linear intermediate frequency stages, up-converters as well as operation of the high powered amplifier at less than maximum power to obtain linear operation is thus avoided.
